Yes, a jug 20L of gas in the back is a must.I made a rule of topping up at every gas station if the tank was less than 1/2 full.Never had to use the spare fuel,but you never know. We took the Laird on the way back but it's a lonely road with lots of wilderness but it's a day shorter on the return.
I'm picking up a extra spare for the trailer as well. When you get to Dawson be sure to take a day trip to Chicken AK I hear they have civilized it with a motel and amusement park and the like. We depart June the 8th and return on the 29th. I got to remember to bring a sign for a post at Watson Lake.
Have a safe trip.

We drove Victoria BC to Dawson via Fort Nelson and return in 2010, and quickly found it wise never to pass a gas station -- try to go "x" number of miles as you would further south before stopping, and they're out of gas, or the generator has broken down, or the place burned down last season but your guidebook doesn't know that. Always drive on the top 1/4 of your tank. We saw some close calls involving other people driving on fumes just making it into a station where there was no gas within 100 miles in either direction, or running out of gas on the Alaska Highway after dark and having to hike 75 miles to get some. Tow truck costs are huge, and there is no cell coverage. Don't take the chance; always fill up when you can!

Your right,but it was my experience that if some one pulled over because of a flat tire or low on gas. There where 5 or 6 vehicles that would stop and see what the trouble was. even I started pulling over to see if I could help. People up North are like that you know. They look after each other even if you plate is out of Province or State.

Where back from our Big White North trip Steveston to Dawson City with a slight detour to Inuvik and a flight into Tuktoyaktuk total of 8,400 kms.
And a stop in at Watson Lake proved there is always room for one more.

We spotted the trailer in Dawson City while we took the truck up to Inuvik.
The reason is the 1400 kms would take 5 years of the trailers life. The gravel and shale road surface is not trailer or RV friendly and real hard on tires. My new BFG All Terrains on the truck are half gone The only Rv's we seen where rentals. While in Inuvik and Tuk we never seen the sun set for 4 days Same in Dawson, I wasn't till we got to Carmack the Sun went down for about an hour or so.I got so use to the daylight I didn't notice for a while. It is a travel Experience you will never forget. The highest gas per/L was $1.86 in Inuvik. Otherwise $1.44 was the norm. Still waiting for the gas bill to come in... Ps/ We also did the top of the world Highway 210 kms to the US border and back to Dawson. It use to be paved but now it's gravel as well and dusty.But worth every km. The picks are from top of the world Highway Yukon / Alaska border

Hi: Devil Dog... Furthest north I've been was Peace River Alberta. That was mid summer 30 yrs. ago and it only got dusk for a few hrs. never really dark. We hope to take a trip out to B.C. in 2014. Might make the Escape Rally in June.
Thanks for posting more pic's. Alf
